The study objective was to determine the relation of prenatal smoking exposure to the use of psychotropic medication up to young adulthood by using population-based longitudinal register data consisting of all singletons born in Finland from 1987 to 1989 (n=175,869). Information on maternal smoking was assessed during antenatal care and received from the Finnish Medical Birth Register. Information on the children's psychotropic medication (1994-2007) was received from the Drug Prescription Register, and the children's psychiatric diagnoses related to outpatient (1998-2007) and inpatient (1987-2007) care were derived from the Finnish Hospital Discharge Register. A total of 15.3% (n=26,083) of the children were exposed to prenatal smoking. The incidence of psychotropic medication use was 8.3% in unexposed children, 11.3% in children exposed to10 cigarettes per day (odds ratio=1.63,95% confidence interval : 1.53,1.74). The exposure was significantly associated with the risk for all medication use and for both single-and multiple-drug consumption even after adjustment (e.g., mothers'severe psychiatric illnesses). These findings show that exposure to smoking during pregnancy is linked to both mild and severe psychiatric morbidity.
